Insofar as-Ijarnf aware there isno satisfactory straining device for use n connect on w th paints which is both slmple and efiect'lve'and which Canreadl will. be seenthat the device is, made up of three main parts, one of 'which' is a lower cylindrical section 10,-a second of which is an 75 upper cylindrical section 11, which telescopes ily be kept in perfectstraining condition. I

One of the objects of thepresent invention is the'provision of astraining device for use in straining paints inparticulanwhich obvi-: ates known and hitherto accepted defects and disadvantages and which provides added ad-* 330 vantages peculiar t'o'itsjown construction Another. obj ect of the invention i s the pro- Vision of. a straining device particularly adaptedforpaints which'ccnsists of two telescoping sections with a removablestraining; I element therein and whichis provided with ,means for releasablv looking all of theparts in secureposition during use.

A further ob 'ect.of theinven'tion is the provision of a straining device particularly 40 adapted-for paintswhich comprises two telescoping sections whichare adaptedito hold a straining elementin place therein, the whole. being provided withreleasable locking means for maintainin the operativeassociation of' the various parts 'during-us'e, A still furtherTobjectis the provision of a straining device particularly adapted for paints which is composed of non-combustible material so'that it maybereadily cleaned by applying theretoacombustible fluid and setform'of my straining device;

Referring now to the drawing'indet'ail,

1 The lower cylindrical section l0 comprises ashort section of ring having therein near the 'top edge' thereof the diametrically -op-' posite apertures 13. ear the bottom edge of said section l O an'd laterally somewhat displaced from said apertures l3- are the diametrically opposite elongated slots 14.

At the'other end of the plate a screw-threaded shank 21 pro- The upper cylindrical section 11 of the straining device is somewhat larger in diameter than the lower cylindrical section 10 and in practice is ust enough larger so that the twomay telescope partially, as shown in the drawing. This upper cylindrical section 11 is provided with diametrically opposite apertures 24 approximately midway or slightly below the horizontal middle and 7 these apertures are so proportioned with re- 10 that the horizontal Walls defining the upspect to the apertures 13 in'the lower section per edges of the apertures in the upper section align'substantially with the horizontal 1 walls defining the upper edges of the aperv known manner to said stationary hinge plates tures in tlie lower section (see Fig. 2). Aside from this the apertures in the upper Section do not further register. with the apertures in the lower section but on the contrary the apertures in the .upper section are shorter andare of less height, so that when the up- J per and. lower sections are assembled, as will be hereinafter more fully explained, the respective apertures take. the relative positions clearly shown in Fig. 2.

As will be observed from the drawing the upper cylindrical section llis provided with an inwardly extending annular flange 25 which be, generally speaking, about midway or somewhat above the horizontal middle of the upper section. The function of this flange will be apparenthereinafter.

Suitably riveted, welded or the like as at, 26 to the walls of the upper section 11 are the hinge plates 27. These may be substantially conventional hinge plates and may or i may not be curved to correspond to the curve of the cylindrical section. Hinged in 27 are the pivotal hinge plates 28 which are suitably longer than the stationary hinge 7 plates aforesaid as will be clear from the drawing. These latter hinge plates 28 may be suitably designed to give an attractive appearance and, as shown, they are further provided with the inward extensions or looking projections 29, which are so arranged that they'project through the apertures 13 and 24 in thecylindrical sections 10 and '11, respectively, i

,The straining element 12 may be a suitablescreening member as shown and is preferably of a circular form appreciably larger than the diameter of either of thecylindrical sections. In practice a number'of these flat circular screening elements are provided and preferably they may be of "difierent meshes so that the proper straining element may be chosen for a given use. This straining element is of considerable strength and is preferably a metallic screening, but at the same time, is bendable. 7 Such an element has been shown in Figs. 1 to 4, inclusive, but in Fig. 5 l have shown a screening element of somewhat different type and one which is of preformed shape. This screen numbered 12' has only a short right angled flange 12 which does not reach as far as the apertures in the sections.

In assembling the straining device, the circular piece of screening 12 is laid over the lower cylindrical section 10 and slidable plates 15 are moved to the extreme right-hand position with respect to their slots. The upper cylindrical section ll'is now placed over said lower cylindrical section 10 in such a way that apertures 24in upper section 11 will assume the position shown in Fig. 2 with respect to apertures 13 in the lower section 10 and for guiding purposes the guide marks 30 are provided on the sections, as is clearly shown in Fig. 1. Cylindrical section 11 is now forced down over the lower cylindrical section 10 with which it partially telescopes and this automatically bends down the extending portions of the straining element alongthe sides of section lO-and the sections are limited as to telescoping action when the flange 25 of the upper section abuts the upper edge of the lower section 10 and the straining element thereover.- Thereupon pressure is placed manually upon the lower extremities of the pivotable hinge plates 28 so that projections 29 are forced inwardly into the apertures and bend a portion of the straining element around as shown. Then while holding said hinge plate as far in as it will go, slidable plates 15 areslid to-the left so that the tionally locked by the prog'ection 29 in the apertures 13 and 24. V

In Fig. 5 the preformed screen is clamped solely between the two flanges 25 and 25 and in this modification the other locking means do not contact the screen itself which is purposely made'with a flange so short that it does not overlie the apertures 13 and 24.

It will thus be clear that'I have provided a simple yet unbreakable and effective strain-V ing device which comprises two telescoping sections with a straining element held therein in operative posltlon and withmeans for locking the sectionsin'position during usebut enabling relea'se thereof either to separate the. sections merely or to separate them for the purpose of substitutingainew straining j element when the-one in use becomes clogged,

fonexample; By arranging the apertures 13 andfle as shown, pa'rticularlyin Fig. 2 I'provide also an efiectivemeans for locking the screen iminovably in position and for. keeping it-taut. This arrangement of apertures in, connection with the tapered.protection 29 on eachv hinge plate 28 providesan unusually efl'ective lock-ing arrangement.

While I haveshown' the sections "and'11 asv circular this is for. convenience. mostly as the device is so dimensioned that itiwill fit over a paint can, for. example. 1 Obviously the device may be made in different sizes to j fit over paint leans ofldiflierent capacities. Furthermore, the device may be made nonround, that' is, polygonal ifdesired and with each plate, said lower opposite apertures, alignable with theapertures in said lower section, yand any preferred number of sides. Whilethe .material is preferably all metal any or all of the parts may be made of fibrous materials cleaning fluid which is a-solvent for the paint or the like is poured freely over the device. which has been removed from the canassoililig fluid then ignited, thus burning off and e ectively cleaning the whole device. 1

Finally, while the devicehas been particularly adapted for use in connection with 5 straining paints it is to be understood that it may also be used for straining other materials. Among these are foodopr'oducts such I as tomatoes, grapes, which'may be crushed directly upon the screen and strained, cran- 9 berries, and other food products or the device may also be used for straining any fluids containing solids-whichare to be separated from the liquid parts thereof. In such cases the material of thedevice may be so chosen 5 that it doesnot corrode in use or contaminate the food orother through. 1 What Iclaim as new and desire to secure product strainedthere which are non-combustible since, when it is desired to cleanv the device, a combustible ciated therewith and the combustible cleanbeing pro- I a member projecting through said slots a straining elementitautly locked in said seclocking iposition.
